Tardigrades: Why water bears could be the first interstellar astronauts

Posted by in categories: health, robotics/AI, space

It’s more likely than you think.


When it comes to interstellar missions, however, there are no plans for crewed missions on the table. While there are proposals for sending robotic missions, sending astronauts to nearby stars and exoplanets simply isn’t feasible yet.

Pfizer pledges shipment of new antiviral COVID pill to Israel — report

Posted by in categories: biotech/medical, health

Pfizer has pledged a shipment of its experimental antiviral COVID-19 pill to Israel, according to a Saturday television report, a week after the US drugmaker said it was engaged in “active discussion” with 90 countries regarding the coronavirus medication.

Prime Minister Naftali Bennett and Health Minister Nitzan Horowitz reached an agreement with the drug company for tens of thousands of doses, Channel 12 news reported. The shipment will be despatched as soon as Pfizer receives FDA approval for the pill, the TV report said.


PM and health minister reach agreement with drug company for ‘tens of thousands of doses’; initial data shows almost 90% efficacy.

“Whispering Gallery” Microresonator Can Measure Individual Nanoparticles

Posted by in categories: biotech/medical, health, nanotechnology

Forget all the nanotechnology devoted to fighting cancer, and just consider that nanoparticles have invaded makeup, anti-odor socks, sunscreen, plastic beer bottles and home pregnancy tests. Now scientists have developed a way to assess the health and environmental impact of such nanoparticles: a tiny microresonator that can detect and measure individual particles smaller than a single virus.

The microresonator is a lab-on-a-chip that harnesses the “whispering gallery” concept that’s displayed by buildings such as St. Paul’s Cathedral in London. The cathedral’s domed gallery can carry whispers easily across to the other side, but normal-volume voices end up garbled after bouncing around the dome multiple times.

Similarly, microresonators can bounce laser light many times around a circular “waveguide,” such as a glass ring. A laser frequency must perfectly fit the circumference of a ring to achieve this whispering-gallery mode.

Apple’s Increasing Focus on Health Seen in Recent Hiring Trends, New Board Member

Posted by in categories: computing, health, security

Apple has been talking for years about the role it wants to play in human health, led by the Apple Watch and its array of health-related features. With the Apple Watch maturing and Apple increasing its integration of health-focused hardware and software, several pieces of evidence suggest the company is positioning itself for an even bigger expansion in that direction.

According to trends compiled by Linkedin and seen by MacRumors, over the past year, Apple’s open job listings in health-related fields have increased by over 220%, with a significant portion of the increase coming in just the last several months. Apple’s health-focused hiring has been the fastest-growing segment for the company over the past year, followed most closely by sales and IT specialists, such as in cloud computing and security, according to the data.

Self-Driving Farm Robot Uses Lasers To Kill 100,000 Weeds An Hour, Saving Land And Farmers From Toxic Herbicides

Posted by in categories: chemistry, health, robotics/AI, sustainability, transportation

The nutrient content of our vegetables is down 40% over the last two decades and our soil health is suffering due to increasingly harsh herbicide use, according to Carbon Robotics founder Paul Mikesell. And farmers are increasingly concerned about the long-term health impacts of continually spraying chemicals on their fields.

But not weeding will cost half your crop, killing profitability.

The solution?

Making science serve humanity: Jennifer Doudna, PhD, says CRISPR gene-editing technology should be accessible to all

Posted by in categories: biotech/medical, genetics, health, science

The path that led Jennifer Doudna, PhD, and her colleagues to the development of CRISPR, the gene-editing tool that has revolutionized science and earned her a Nobel Prize, started with their deep curiosity and drive to understand how the most basic building blocks of life function.

When Doudna first decided to investigate precisely what systems bacteria use to adapt their immune systems to fight off viral infections, she had little expectation that the findings would ultimately provide the key to technology that could be used to safely alter genetic code.

“All of us [on the research team] realized that what had started as a fundamental research question was morphing into a very different kind of project; namely, one with enormous technical potential and also risks and opportunities that we had not appreciated when we started the work,” Doudna explained during a conversation with J. Larry Jameson, MD, PhD, chair of the AAMC Board of Directors and executive vice president of the University of Pennsylvania Health System, at the opening plenary of Learn Serve Lead 2021: The Virtual Experience, on Monday, Nov. 8.

Brain Structure is Key to Understanding Human Cognition

Posted by in categories: biotech/medical, computing, health, neuroscience

A CNS 2021 provided an incredible opportunity to learn more how the anatomy and integrity of brain networks impact higher-level cognition.


In the 19th and 20th century, cases of individuals with brain injury, such as Phineas Gage or Henry Molaison, have advanced our understanding of the relationship between the anatomy of the brain and its function. Back then, methods were limited to investigate whole-brain structure and function. Now, cognitive neuroscientists have some ability to visualize and measure activity of the whole brain at once, as well as the computational tools to investigate complex network-level relationships between brain structure, brain function, and behavior.

As a doctoral student working on stroke recovery, attending the CNS 2021 symposium led by Danielle Bassett was an incredible opportunity to learn more about some of the most recent methods that have been developed to understand how the anatomy and integrity of brain networks impact higher-level cognition. Strokes highly disrupt anatomical and functional connectivity, leading to cognitive and motor impairments. In individuals with post-stroke language impairments, namely aphasia, evidence shows that the more functional brain networks recover an organization similar to healthy individuals the better the recovery (Kiran et al., 2019). Understanding the relationship between brain structure and function in health and disease is therefore essential to develop appropriate treatments.

China struggles to contain Delta variant of COVID

Posted by in categories: biotech/medical, health, policy

China’s zero-COVID-19 policy is showing strain as health authorities struggle to contain the growing spread of the Delta variant.
At least 1,000 locally-transmitted infections have been reported since mid-October in 20 provinces, prompting strict quarantine periods and area-specific lockdowns.
The onset of winter in China’s north is also helping disperse the disease.
